A recognized organizational role (not merely a job title) held by an individual or group entrusted with the installation, configuration, ongoing operation, and maintenance of an information system or network on behalf of an organization. What distinguishes it from ordinary users or even managers is the elevation of privilege it entails — the role covers responsibility for overseeing the day-to-day operability of a computer system or network and normally carries special privileges including access to the protection state and software of a system. Authority documents use the term to assign specific security duties: the individual is responsible for the installation and maintenance of an information system, providing effective information system utilization, adequate security parameters, and sound implementation of established policy and procedures; and in workforce-role frameworks such as CISA's NICE taxonomy, the role covers setting up and maintaining a system, including installing, configuring and updating hardware and software; establishing and managing user accounts; overseeing backup and recovery tasks; implementing operational and technical security controls; and adhering to or

Advisory only. A term this product ships is defined by an authority document, not by a search result.
